Considering the importance of organic fertilizers application and the necessity of minimizing the use of inorganic fertilizers, this experiment was conducted in order to study the possibility of replacing vermicompost and poultry manure instead of chemical fertilizers in the production of two improved chickpea cultivars under dryland conditions. The experiment was laid out in a factorial arrang...
Background & Aim: Nowadays, tendency to agricultural biotic product sustainable agriculture instead of chemical fertilizers has been going up in all over the world. So, most pharmaceutical industries prefer to use raw material which is produced from organic and stable system. Producing organic medicinal plants, such as peppermint, seems important in economical, ecological and bio e...

In order to study the effect of phosphate biofertilizer and chemical fertilizers of nitrogen, phosphorus and sulfur on some growth and yield components of Camelina sativa L., a study was conducted based on a factorial experiment; this was done in a randomized complete block design with three replications at Kazeroon during the 2016 growing season. Treatments included bio-based phosphorus (P)...
BACKGROUND: Among the environmental stresses soil salinity is a widespread environmental problem that has been found to affect more than 77 million hectares or 5% of the cultivable land of the universe. Potassium has a positive role in plant growth under saline conditions, because this element plays an essential role in photosynthesis, osmo regulatory adaptations of plant to wa...
In order to evaluate the effects of inoculants and chemical fertilizer on quantitative and qualitative yield, a bread wheat cultivar treated with Azotobacter, arbuscular mycorrhiza fungi (AMF) and nitrogen sources by using split plot on the basis of randomized complete block design with three replications in Fars Agricultural Research Station during 2007-2008. Main plots consisted of nitrogen f...
BACKGROUND: Nitrogen is a basic plant component, playing a decisive role in the intensification of plant production. Bio-fertilizers play a very significant role in improving soil fertility by fixing atmospheric nitrogen, both, in association with plant roots and without it, insoluble soil phosphates and produces plant growth substances in the soil. OBJECTIVES:</s...
BACKGROUND: Organic farming has emerged as important priority area globally in view of growing demand for safe and healthy food and long term sustainability and concerns on environmental pollution associated with indiscriminate use of agrochemicals. Nano fertilizers can be easily absorbed by crops and may exhibit a prolonged effective duration of nutrient supply in soil/crop co...

In order to study the effect of application of nitrogen, phosphorus and biologic fertilizers on yield and yield components of native bean, an experiment was conducted as factorial in randomized complete block design with three replications in Lahijan, northern Iran in 2013. Treatments consisted of chemical nitrogen fertilizer (0, 60 and 120 kg ha-1 urea), chemical phosphorus fertilizer (0, 40 a...
